若以声音朗诵真言,则此持诵之祭称为“语诵”(vācika)。应当柔和而缓慢地诵出真言,只令双唇微微动摇。
Suta Goswami (narrating the Purāṇic teaching on japa to the sages of Naimiṣāraṇya)
It prescribes the correct method of vācika-japa (audible mantra repetition), a foundational discipline supporting liṅga-pūjā by purifying speech (vāk) and stabilizing devotion through regulated recitation.
By framing japa as a yajña, it implies that communion with Pati (Śiva) is attained through disciplined offering—here, the offering of sound and intention—guiding the paśu away from pāśa through sādhana.
Vācika-japa: slow, gentle audible recitation with minimal lip movement—an outer-to-inner training that can mature into subtler japa forms aligned with Pāśupata-oriented sādhanā.
